Two funds head-to-head: live engine reads, trailing performance, and holdings overlap from SEC filings. An engine-read comparison — not a recommendation.
From each fund's SEC N-PORT filing (2026-08-25 / 2026-08-28), computed on the 1528 of 2497 and 1813 of 3528 equity positions matched to the QuantLogix stock universe — a lower bound, never an estimate.
QuantLogix's 5-factor engine currently reads iShares Core S&P Total U.S. Stock Market ETF (ITOT) at 49/100 (neutral) and Vanguard Morningstar Total Stock Market ETF (VTI) at 65/100 (buy).

On trailing price performance, VTI leads over the last year (+18.6% vs +18.6% for ITOT). By filed portfolio weights, at least 61.7% of the two funds overlaps across 1470 shared positions. Signals recompute throughout the trading day — the balance can shift with the tape.
